Abstract :
In this paper the FFH-OCDMA system is modeled and studied for its suitability for local access upgrade with WDM at the backbone. Throughput comparison of different OCDMA schemes have shown FFH-OCDMA scheme to be suitable for high traffic loads. Accurate modeling of the FFH-OCDMA system is necessary to analyze the OCDMA/WDM system considering the WDM non-linearities and the physical layer impairments. Hence in this work FFH- OCDMA system is modeled and its BER performance studied. The effect of modeling the fiber Bragg grating (FBG) as an ideal filter as well as using an accurate model based on coupled mode theory, on the BER performance is compared.
